From His Cold Dead Hands: A Vulgar Pluck Mystery

Some people just need shootin'.

When a girl turns up at their office, young private investigator, Vulgar
Pluck, and his enigmatic and arthritic boss, Emma Speel, agree to take
her case. And find themselves caught up in an unholy mess. Femme Deckard
wants them to find the gun that was used to kill her brother.

But Femme isn’t giving them the whole story, and following the leads
brings the investigators into conflict with a gun-nut, a mysterious
Harley-riding pale-skinned cowboy, a group of manic Satanists, a
powerful arms manufacturer and an eerie Jamaican gangster, most of whom
are looking for either Femme’s gun or a missing quantum physicist – or both.

By the time Pluck and Speel realize what they’ve got tangled up in,
they’re too caught up to get out. They are pieces in a frightening game,
played by ruthless and malevolent forces. Suddenly, solving the case is
the least of their worries . . .
